147 7' ORIYf) Patented Dec. 12, 1944 nnvmzrrsmcimsemr'nnwcs I Harvey HJHall, Denver, 0610. v v duplication June'3, 1944, Serial No.,538;:8 1 I j 5 cla m (clean-"33) invention relates to an advertising device and has for its principal .objectfthe provision of aisimple, inxepensive, and compact unit for ,well

successively displaying plurality (of illuminated advertisingsigns or :cards.

V otheraobiect-of then-invention is to ,provide adevziceof character in which all, operating mechanism will ,be enclosed within a rotating drum carrying the display .ads so, as a to employ space whichwouldotherwise be wasted andso as toreduce the overall size of :the device.

,,Other objects are: to -eliminate alleicpensiye Geneva gears, -.ac'tuating =ratchet pawL start and stop switches, and other i expensive and intricate operatingQdevices'; to provide means-whereby the advertising material can .be quicklwand easily changed; fan d to provide 4a rotatable housing.

which willenable (the. display twindow to :be :directed inanydesireddirection.

'lither {objects -.andadvantages reside in v the detail cons'truction of the invention, which is designed .for simplicity, economy, and -efliciency. These will Jaeconie more apparentfrom the following descr ption.

' been described and illus rachet coincides to the number of plates IT; in this case there being six teeth in the rachet. A friction clutch consisting of two friction disks 34 ispositioned between the cam 32 and the rachet 33 so that rotation of the former will be fric-j tionally transmitted to the latter to rotate the drum. The cam 32 may be forced toward the rachet 33 in any desired manner; suchas by means of a spring washer 35 acting against the motor platfortip-maintain the frictional en' gagementl'l v.

It can be readily seen that the entire series of advertising plates will normally rotate with the cam 32 under the influence of the, motor 26.

is impeded in any manner, the cam32- will con: tinue to rotate, allowing the clutch to slip so i that the rachet' 33 will remain stationary.

'Means are provided for holding the drum at intervals. This is accomplished by means of a 0 hooked rachet pawl 36 which is mounted at one extremity on a hinge pin3l at the extremity of the motor platform 30. The other extremity of the pawl terminates in a' wide hook which overlies both-the cam- 32 and the rachet 33. In operationthe hookof -the pawl 36 engages one of the' t'eeth of the-rachet33 to hold the drum stationary. The cam 32 continues to rotate, however, so that it will gradually lift the pawl 36 until the'latter releases the-rachet tooth, allow- 0- ingthe drum to rotate with the cam 32 for 60 when the pawl 36-will engage the next tooth of the rachet.- I

Thus it will be noted that the pawl 36 is lifted once at each complete revolution of the cam 32 allowing the -rachet .33 to rotate with the cam for one-sixth of a revolution; This acts to successivelydisplay the various advertisements on the 'plat'e's I] in the window l5 and to allow them; to remain stationary in the window until 40.

thecam: 32 has made one revolution.

Current'for-the motor 26 and the lamps 2 is fed to the-device-through a suitable conductor, cord 38 which leads into the hollow interior of the shaft I I, as shown in Fig. 3, and from thence point so that a complete revolution'thereof is allowed before they pawl 36 is'released. It can of course-bemade with two 'or morehigh points to release the .pawl at more frequent intervals, if desired. I w
